Ignition Coil Problems & Advice

Heres another post about coil problems on Mercs and a word of advice: Take your motor to an authorized Mercury repair shop, even if the shop is miles away from your neighborhood shop. It could save you a lot of money and a lot of grief.Five weeks ago I took my Pantera Classic and Mercury 200 EFI to my usual guy (not an authorized Mercury repair shop) just a few miles away. I wasnt able to get up on plane and he diagnosed it as a bad ignition coil. Three weeks and $266 later (thats right, 3 weeks to get a simple part), I took it back out to the lake and it ran just as bad. A friend recommended an authorized shop so I took it to them even though it was much farther away. They ran a diognostics test and found that the #5 coil was bad. They contacted their Mercury tech who authorized replacement of the remaining five coils at no cost to me even though the motor has been out of warranty for nearly two years. I paid for the overnight shipping and picked up the boat one week from the day I took it in. Turns out my neighborhood guy never even discussed my coil problem with Mercury. He claimed Mercury dropped the ball in shipping the replacement coil and he had to get it from another dealer. I contacted Mercury and they claim to have no record of being contacted by him. So live & learn I guess!

I have always thought it pays to go to a certified Mercuy tech. Luckily, Ive never had any major issues, but your advice is very good!! If I feel the need…Ill take mine 12 hours back to Indiana to have Sherm look at it!!

Mercury has a thing going on about the coil problems they have had-They are replacing all 6 coils on motors that come in with a bad coil-My #2 went out when boat was brand new-About a month ago my #6 went out and Mercury told dealer to replace all 6 coils.

They appear to be through the coil issues on newer products, thanks to a vendor alteration. The ones we see now are on equipment over a year old from production.

Alright Ill ask. What are the engine characteristic with coil issues? I know I dont have a clue. Does the motor not turn over?Last edited by Flyswatter on November 25th, 2010, 4:36 pm, edited 1 time in total.

They are usually slow on top end or hole shot.

when mine dropped a coil last month, replacement parts were on Natl backorder at the time. My servicing dealer (not a BCB dealer, but a Merc Platinum dealer with the highest level service certs) was cool enough to snag parts from an instock new engine to get me back on the water.Advantages are taken, not handed out…

flyswatter-the computer will not let motor go to top end-when idling around you can fill motor running rough-this last time my motor would not push boat up on trailer

I have had all 6 Replaced on my Verado ( out of my pocket ) during the last 18 months and now its starting to go through them again , just replaced # 5 cyl. again ..exactly 1 yr to the date it went out the 1st time . Really getting expensive at $ 100.00 each ..plus labor . Merc should stand behind this as I know from talking to my Merc cert. Mech that Im not the only one this is happining to , but there only guarenteed for 1 yr . I have always had a black motor on the back of every boat I have owned ( 8 ) but my next one may very well be a different color !
